Sir, privacy leaks here as all the DNS requests are showing what you look at:

Tht's why URLs are used elsewhere. https://nostrudel.ninja/#/u/npub1xtscya34g58tk0z605fvr788k263gsu6cy9x0mhnm87echrgufzsevkk5s/notes

nostrudel.ninja is a domain name, publicly resolved and anyone on the way to (or only, in case of DoH or DoT) your DNS provider can see you are accessing nostrudel.ninja, but all the rest is encrypted between your client and the destination web server.
